If the question meant that choosing a marble for five hundred times ; then the calculation is stated below:
Answer:
214
Step-by-step explanation:
Given that :
Probability of picking a red out of a bag of colored marble = 3 : 7 ; that is 3 / 7
P(red) = 3 / 7
If the number of picks (with replacement) = 500
Then, the approximate number of red marbles chosen will be :
P(red) * number of picks
3/7 * 500 = 214.285
Approximate Number of red marbles chosen = 214

= - 312/40
= -7 32/ 40 = -7 4/5 or 7.8
